MP
From A KoL Wiki

MP
MP can stand for one of three things, based on a player's class:
- Muscle/Muscularity Points: Seal Clubber, Turtle Tamer
- Mysticality/Mana Points: Pastamancer, Sauceror
- Moxie/Mojo Points: Accordion Thief, Disco Bandit
In all cases, though, MP are used for casting skills.
See MP Increasers for details as to how you can increase your maximum MP.
MP is regained at rollover and by resting or relaxing in your campsite, consuming various items, or with the aid of your familiar. See MP Restorers for full details as to how MP can be restored.
